Description

Technical Field

[0001] This utility model relates to the field of building envelope heat transfer detection technology, and in particular to a device for detecting the heat transfer coefficient of a green and low-carbon building envelope. Background Technology

[0002] The heat transfer coefficient of the building envelope is a key indicator for measuring the thermal insulation performance of building envelopes such as walls and roofs. It represents the amount of heat transferred per unit time per unit area when the air temperature difference between the two sides of the building envelope is 1°C under stable heat transfer conditions. The smaller the value, the better the thermal insulation performance. It is an important parameter for green and low-carbon building design and energy-saving assessment.

[0003] Existing heat transfer coefficient testing devices for building envelopes have some shortcomings in practical use:

[0004] On the one hand, the temperature sensor does not fit tightly against the wall surface, making it susceptible to interference from the ambient air, resulting in a large temperature detection error and affecting the accuracy of the heat transfer coefficient calculation; on the other hand, the heat transfer efficiency between the heat transfer plate and the wall is low, making it impossible to accurately capture heat transfer data.

[0005] On the other hand, the testing device lacks a stable support structure, and is prone to displacement due to external force during the testing process, resulting in poor adhesion between the heating box and the wall. This not only affects the testing accuracy, but may also cause equipment damage due to the device tipping over. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a green and low-carbon building envelope heat transfer coefficient detection device, which overcomes the shortcomings of the prior art and effectively solves the problems of large temperature detection error and lack of stable support structure of the detection device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A green and low-carbon building envelope heat transfer coefficient testing device includes a heating box attached to both sides of the wall surface. The heating box contains heat flow plates, and a rectangular frame is fixedly connected to the outer wall of the heat flow plates. A first sleeve is welded to both outer walls of the rectangular frame, and a temperature sensor is installed on the inner wall of the first sleeve. An aluminum foil adhesive paper for adhering to the wall surface is adhered to the outer wall of the temperature sensor. Side supports and a front baffle are respectively provided on the two outer walls and one outer wall of the heating box.

[0009] Preferably, both the side support and the front stop include a sleeve hinged to the outer wall of the heating box, a telescopic rod slidably connected to the inner wall of the sleeve, and a support pad welded to the bottom outer wall of the telescopic rod.

[0010] Preferably, a fastening knob is screwed onto the outer wall of the sleeve, and the fastening knob is tightly attached to the outer wall of the telescopic rod.

[0011] Preferably, a thermally conductive silicone grease sheet for adhering to the wall surface is tightly attached to one side of the outer wall of the heat transfer plate.

[0012] Preferably, the outer walls on both sides and one side of the heating box are fixedly connected with a second clamping sleeve, and the inner diameter of the second clamping sleeve is adapted to the outer diameter of the sleeve.

[0013] Preferably, a temperature display screen is installed on one outer wall of the heating box, and the temperature display screen is connected to the temperature sensor via a signal line.

[0014] Preferably, a main controller is connected between the two heating boxes via a signal line, and the heating boxes and the heat exchange plates are connected via a signal line.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The green and low-carbon building envelope heat transfer coefficient detection device designed in this paper uses aluminum foil adhesive paper to tightly attach the temperature sensor to the wall surface, which reduces the interference of ambient air on the detection and improves the accuracy of temperature data. At the same time, the thermal grease sheet on one side of the heat flow plate enhances the heat conduction effect with the wall, making the heat flow data more accurate. Combined with the main controller's analysis and processing of data, the accuracy of heat transfer coefficient detection is greatly improved.

[0017] 2. The heat transfer coefficient testing device for the green and low-carbon building envelope structure in this design allows for flexible adjustment of the support height through the cooperation of the sleeve and the telescopic rod. The support pad increases the contact area with the ground, ensuring that the heating box is stably attached to the wall. When not in use, the telescopic rod can be retracted into the sleeve, and the sleeve can be inserted into the second sleeve, reducing storage space and making it easy to carry and transport.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5 Example 1: A device for detecting the heat transfer coefficient of a green and low-carbon building envelope includes a heating box 1 attached to both sides of a wall. The heating box 1 has a heat transfer plate 2 inside, and a rectangular frame 3 is fixedly connected to the outer wall of the heat transfer plate 2. The outer walls of both sides of the rectangular frame 3 are welded with a first sleeve 4, and a temperature sensor 5 is provided on the inner wall of the first sleeve 4. An aluminum foil adhesive paper 6 for adhering to the wall surface is adhered to the outer wall of the temperature sensor 5. A thermally conductive silicone grease sheet 13 for adhering to the wall surface is tightly attached to one side of the outer wall of the heat transfer plate 2.

[0026] The heating chamber 1 is attached to both sides of the wall, providing a stable temperature environment for heat transfer detection. The heat transfer plate 2 inside detects the heat flow through the wall. The rectangular frame 3 fixes and protects the heat transfer plate 2, preventing displacement or damage due to external impact. The first clamping sleeve 4 is fixed to both sides of the rectangular frame 3 for mounting the temperature sensor 5, ensuring its stable position. The aluminum foil adhesive paper 6 on the outer wall of the temperature sensor 5 has good adhesion and thermal conductivity, allowing it to adhere tightly to the wall surface while reducing the influence of external temperature on the sensor, ensuring the reliability of the detection data.

[0027] In this embodiment, the temperature sensor 5 is tightly attached to the wall surface by the aluminum foil adhesive paper 6, which reduces the interference of ambient air on the detection and improves the accuracy of temperature data. At the same time, the thermal grease sheet 13 on one side of the heat transfer plate 2 enhances the heat conduction effect with the wall, making the heat transfer data more accurate. Combined with the analysis and processing of the data by the main controller 16, the accuracy of heat transfer coefficient detection is greatly improved.

[0028] In the second embodiment, the outer walls on both sides and one side of the heating box 1 are respectively provided with side support members 7 and front baffle members 8. The side support members 7 and front baffle members 8 each include a sleeve 9 hinged to the outer wall of the heating box 1, a telescopic rod 10 slidably connected to the inner wall of the sleeve 9, and a support pad 11 welded to the bottom outer wall of the telescopic rod 10. A fastening knob 12 is screwed onto the outer wall of the sleeve 9, and the fastening knob 12 is tightly attached to the outer wall of the telescopic rod 10.

[0029] Side support 7 and front stop 8 are respectively set on both sides and one side of heating box 1. Sleeve 9 is hinged to the outer wall of heating box 1 and can be flexibly rotated to adjust the support angle. Telescopic rod 10 slides in sleeve 9 and can adjust the support height according to the flatness of the ground. After adjustment, it is locked by fastening knob 12 to prevent telescopic rod 10 from loosening. Support pad 11 is made of rubber to increase friction and prevent the device from sliding.

[0030] In this embodiment, the side support 7 and the front stop 8 can be flexibly adjusted in height by the cooperation of the sleeve 9 and the telescopic rod 10. The support pad 11 increases the contact area with the ground to ensure that the heating box 1 is stably attached to the wall. When not in use, the telescopic rod 10 can be retracted into the sleeve 9 and then the sleeve 9 can be inserted into the second sleeve 14, which reduces the storage space and makes it easy to carry and transport.

[0031] The heating box 1 has a second ferrule 14 fixedly connected to both outer walls and one outer wall, and the inner diameter of the second ferrule 14 is adapted to the outer diameter of the sleeve 9.

[0032] The second sleeve 14 is fixed to the outer wall of the heating box 1. Its inner diameter is adapted to the outer diameter of the sleeve 9. When the device is stored, the sleeve 9 can be inserted into the second sleeve 14 to fix the side support 7 and the front stop 8, thereby reducing the space occupied.

[0033] A temperature display screen 15 is installed on one outer wall of the heating box 1, and the temperature display screen 15 is connected to the temperature sensor 5 via a signal line. A main controller 16 is connected between the two heating boxes 1 via a signal line, and the heating box 1 and the heat flow plate 2 are connected via a signal line.

[0034] Temperature display screen 15 is installed on one side of heating box 1 and connected to temperature sensor 5 via signal line. It can display the temperature data of the wall surface in real time, which is convenient for operators to observe. The main controller 16 is connected to the two heating boxes 1, receives the signals from heat flow plate 2 and temperature sensor 5, and calculates the heat transfer coefficient through built-in algorithm to improve detection efficiency.

[0035] Working principle: During testing, the two heating boxes 1 are first attached to the two sides of the wall respectively. The support height is adjusted by the side support 7 and the front stop 8 to make the heating box 1 stably attached to the wall. The support pad 11 ensures that the device does not slide. The temperature sensor 5 is attached to the wall surface by the aluminum foil adhesive paper 6. The thermal grease sheet 13 on one side of the heat flow plate 2 is tightly attached to the wall to enhance heat conduction.

[0036] When the heating box 1 is working, the temperature sensor 5 detects the temperature on both sides of the wall, the heat transfer plate 2 detects the heat flow through the wall, and the temperature data is displayed on the temperature display screen 15 in real time. The main controller 16 receives the signals from the temperature sensor 5 and the heat transfer plate 2, performs calculations according to the heat transfer coefficient calculation formula, and obtains the heat transfer coefficient of the building envelope.

[0037] After the test is completed, loosen the fastening knob 12, retract the telescopic rod 10 into the sleeve 9, and then insert the sleeve 9 into the second sleeve 14 to facilitate the storage and movement of the device.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
